Base-load backup source such as fuel cell can help the micro-grid system with renewable energy sources such as wind improving power supply security However fuel cells have slow transient response which cannot respond instantly to load changes A dynamic storage system should be a good option to amend for this drawback Supercapacitors have fast transient response and can store and supply power making it suitable for serving as a dynamic storage system The supercapacitors generally operate at low voltage and high current The voltage difference between the supercapacitor and the DC bus voltage is considerable so the converter requires high step-up and step-down voltage capabilities The DC-DC bidirectional dual active bridge converter features bidirectional power flow high step-up and step-down voltage ratio as well as electric isolation These characteristics are right for supercapacitor’s application This thesis presents the integration of the fuel cell and a 500W supercapacitor storage system Simulation and field test validate the feasibility of the hybrid system in response to various load change patterns
